IMPROVEMENT IN MAGAZINE COOKING-.STOVES.

Specification formingpart of Letters Patent No. 168,047, dated September21, 1875 application filed March 4, 1875.

To all whom it may concern:

Be it known that we, JOHN S. PERRY, AN-

DREW DICKEY, and ROBERT Z. LIDDLE, all of Albany, county of Albany andState of New York, have invented certain Improvements in Stoves, ofwhich the following is a specification:

The main object of our invention is to so combine a culinary attachmentwith an illuniinated heating-stove that the structure of their openingsand dampers. Fig. 4, Sheet 2, 4

is a vertical section of the'stove and culinary attachment connectedtogether; Fig. 5, a sectional plan on the line 3 4 Fig. 6, a sectionalplan on the line 5 6; and Fig. 7,-a perspective View.

As regards the general conformation of the stove proper, it is similarto the ordinary illuminated heating-stoves now in common use, having anouter casing or shell, A, composed of the followingparts: the cylinder12, containing the magazine, and resting on the ring of the upperilluminating-section c, which incloses the combustion-chamber the lowermica section d, containing the fire-pot, and'iuclosing, with thebase-section e, the ash-chamber and ash-pit; and the hollow base f,which contains the flues, explained hereafter. At the rear of the stoveis the hollow projection F, terminating at the top in the exit-pipe a,-

for the escape of the products of combustion.

G is the culinary attachment, constructed for application to the rear ofthe base-section of the stove, to which it may be secured by suchfastenings as will permit its ready disconnection from the same. Thisattachment has an oven, 9, flues P, Q, andl. between the culinaryattachment is connected to the stove that these openings d 0, and f areof any service, as will appear hereafter, the said openings being closedby removable plates 12, when a simple heating'st ove, without theculinary attachment, is required. Although we prefer to so construct thecombined heating and cooking stove that the culinary attachment may bereadily connected to, and disconnected from, the heating portion, thetwo may be so constructed as to constitute permanent parts of eachother. In the casing L over the top of the oven there are openings 0 forthe reception of culinary vessels, which are heated from the same sourcewhich heats the oven g. a

H is the fire-pot suspended in the ashchamber within the lower micasection cl, the sides of this fire-pot being vertical, or nearly so,from the upper edge to about the line 00, below which the sides,together with the projections or'fingers h at the base of the firepot,either together or separately, are curved inward and downward. As thisfeature forms the subject of a separate application for a patent tiledby J. S. Perry, further description of it will be unnecessary.

It will be seen on referring to Fig. 3 that the interior of theprojection F at the rear of the stove is separated by a verticalpartition, 19, into a descendingflue, 10 and ascending flue 12 Each ofthese flues communicates with the combustion-chamber through an openingin the wall of the same, and the line 12 also communicates with theexit-opening a but a damper, k, can be so adjusted as to close thecommunication of this flue p with the exitopeninga, in which case theproducts of com bustion must pass off directly from thecombustion-chamber to the chimney, or it may be so adjusted as to closethe opening between the flue p and the combustion-chamber, in

which case the products of combustion must necessarily pass into thedescending fiuep which communicates with a horizontal flue, t,

in the hollow basef. The interior of this hollow base is devoted to twofines, t and t, between which is a partition, V, an opening in thelatter near the front of the base forming a communication between thesefines and the fine 1', communicating with the ascending fine,

the outer casing L intervenes the lower flue .1, the rear fine Q, andupper fine T, and the attachment is so constructed that it shall fit.snngly against the rear of the stove, the upper ifiue T of the ovencommunicating with the ascending fiue 10 through openings al while thelower flue 1 of the attachment shall communicate through the opening 0with the baseflue t, and also through the opening f with the descendingflue 132, when the adjustment of the damper it permits suchcommunication. .In kindling a fire in the stove with the cull .naryattachment the damper It should, in the first instance, be turned down,so that the products of combustion may pass directly from thecombustion-chamber to the exit-pipe, and after the fire has beenthoroughly kindled the said damper It should be turned up,

when the products of combustion will pass ,from the combustion-chamber,through the openingp, down the descending fiuep thence .into the fiue tin the hollow base f, then into the fine t, thence through the opening6' into the lower fine P of the oven, up the rear fine Q of the same,along the upper fine T through .the opening d into the ascending fine p,and

.through the latter to the exit-pipe a. Thus the products of combustion,by the co-operation of the fines of the stove proper \vith those of theoven, impart the desired heat to both .without any additionalconsumption of fuel,

and produce at the same time a perfect baking-oven, g, and boilingappliances.

, Should it be desirable to heat the oven rapidly by first directing theproducts of combustion around the same, this can readily be accomplishedby closing the damper k in the flue 1), opening the damper 7c in fine 12when the products of combustion will pass down the latter flue throughthe openings f at the base of the same into the tine P under the oven,thence upward through the fine Q at the rear of same, and fine T at thetop of the .oven, to the opening d in fine 19 through which they escapeto the exitv a. It will thus be seen that by this simple arrangement theproducts of combustion can be thrown first into the hollow base andthence around the oven, or first around the latter, if a more intenseheat shall be desired for culinary purposes.

The products of combustion in passing through the fines P, Q, and T,surrounding the oven g, are distributed so as to most effectually heatthe surfaces of the latter by the introduction at the desired points ofsuitable fine-strips, one of which is shown under the oven bottom at 11in Fig. 5, Sheet 2.

WVhen the culinary attachment is connected to the stove two chambers, 01(1 are formed by the extension of the walls of the former to thebase-section of the latter, and these chambers we utilize by making themthe medium to furtherincrease the heat in the oven without additionalfuel, and also for ventilating the same. Air is permitted to enter eachof these chambers through openings w, and, becoming highly heated bycontact with the surfaces of the base-section of the stove and those ofthe projection F containing the descending and ascending fines, passesthrough openings w into the front of the ovenand near the top, andescapes from the same through one or more openings, y, at the rear ofthe oven and near the bottom into the rear flue Q, whence it passes offwith the products of combustion to the chimney. The outlet-openings 3are covered with self-adjustable valves 3 Fig. 7, which open or closeaccording to the degree with which the heated air circulates through theoven, thus regulating the heating and ventilating of the same. The oven9 is thus supplied with a constant circulation of heated air, whichthoroughly ventilates it.

We do not confine the openings w, 'w, and y to the position shown, butreserve the right to so place them as to produce the best prac ticalresults. The openings w may be made in the walls of the culinaryattachment at the point indicated by the dotted line on Figs. l-

and 2, Sheet 1, and the openings w and y may have their positionsreversed from near the top to near the bottom of the oven, and from nearthe bottom to near the top of the oven, or these openings w, w, and 3may occupy such relative positions in the structure as shall insuretheir most perfect co-operation to facilitate the heating andventilating of the oven g. l We do not claim the combined fire-pot andgrate shown in the drawing, and briefly a1- luded to in the first partof this specification, inasmuch as a separate application for a patentfor this feature was filed by J. S. Perry on the 24th day of June, 1875;but

We claim as our invention- 1. The combination of a culinary attachment,having fines and openings, substantially as described, with aheating-stove, having an ascending and descending flue upon the rear,and openings by which the said flues may be made to co-operate withthose of the culinary attachment, all substantially as and for thepurposes specified.
